Filed Apr. 19, 1960, Ser. No. 23,173 13 Claims. (Cl. 1Z0-4B Thisinvention relates to marking pencils and more particularly to animproved marking pencil device having a self-contained sharpener thereinwith improved means for feeding the pencil core to the Sharpener. t

Marking pencil devices employing soft crayon or waxlike cores used formarking china and for cosmetic purposes such as eyebrow pencils, whichpencil devices employ feeding mechanisms to feed the pencil core from acase, are well known to the art. It is also known to the art to employvarious types of sharpening mechanisms which are contained within a capforming a part of the case enclosing the pencil core. This isnecessitated by the fact that such pencil cores are of soft wax-likesubstances which will not retain the type of point required for markingor cosmetic purposes. Such prior art devices possess certaindisadvantages, however, particularly disadvantages due to the relativelysoft nature of the pencil core which softness further increases with arise in temperature. Accordingly, due to this characteristic of thecore, continuing stresses imparted thereto will cause damage ordeformation of the core, or clogging of the device. In addition, priorart devices are in general rather cornpleX structures which do not lendthemselves readily to mass production. Although not particularly limitedthereto the present invention is specifically designed for and has itsmajor utility as an eyebrow pencil, and accordingly, the invention willbe described throughout in connection with such use.

In co-pending application `Serial No. 530,993 led August 29, 1955 byWalter iP. Spatz entitled Marking Pencil, now Patent No. 2,941,508,there is disclosed and claimed an improved construction for eyebrowpencils which utilizes a one-way latch device to provide a forwardmovement of the slidably splined pencil core into a conical Sharpenerpositioned within the cap for the device, such that when the cap isrotated on the barrel enclosing the pencil core, the latter is broughtto a point. Essentially, the device of the co-pending applicationincludes a barrel with a tubular support therein which is actually apart of the barrel. This support is adapted to receive the pencil corewhich is propelled in a direction forwardly of the barrel by a feedingmeans that includes a pusher rod and a spring bearing thereagainst. Aone-way latch device in the form of a U-shaped latch springhas an`direction.

Mice

the barrel -an end portion of the cap operatively moves the operatingmember to displace the elongate leg in a rearward direction and free theintermediate portion of the latch from the pusher rod and allow thespring to move the rod and pencil core in a forward direction. Rotationof the cap causes the Sharpener to form a point on the pencil since thespring constantly urges the pusher rod and pencil core forwardly against-the Sharpener until the point has been completed. When the capcontaining the Sharpener is removed from the barrel, as when the pencilis to be used, the elongate` leg of the latch is free to move forwardlyof the barrel to allow the intermediate or base portion of the latch toresume its inclined position and grip the pusher rod to prevent ,thespring from further propelling the rod and .the pencil in a forwardAccordingly, itcan be seen that the pencil core is released and movedforwardly` into the Sharpener whenever the cap is mounted thereon, andthat the pencil core can be pointed after the cap is oriented on thebarrel. Although this prior construction is 'eminently satisfactory inmost respects, the present invention provides an improved device ofsimplified construction which relieves the pencil core of impressiveforces when the sharpening 1s not occurring.

It is an object of the present invention to provide an improvedmarkingpencil device having a Sharpener positioned within the cap thereof whichSharpener ,can be employed` to sharpenthe point of the pencil coreselectively whenever desired or required.

It is another object of the present invention to provide an improvedmarking pencil device employing a selffeeding mechanism which mechanismwill feed the pencil core to the Sharpener only upon express actuationand which will maintain the` point of the pencil at a proper positionfor use.

Another object of the present invention is to provide a marking pencildevice of the type described wherein the pencil core is fed forwardly toa `required position but whichF has no compressive forces thereon whenthe pencil core is not being sharpened. t Accordingly, the relativelysoft marking material forming the pencil core is `not-subject to damagedue to stresses imposed'thereon opening through the base of the U withthe pusher rod extending therethrough. This latch is of theself-energiz- `ing type and is adapted to grip the pusher rod to preventthe spring from moving the rod and the pencil encased The latch springis released from the pusher rod whenever an operating member mounted onthe `barrel is engaged by the` cap of the marking pencil, which capmisadapted to be rotatably mounted over the forward portion or nose of thebarrel. The operating member moves one leg of the U-shaped latch springto move thefbase portion of the latch spring containing the opening froman inclined v @position to a position moreat right angles to the axis.ofthe pusher rod and pencil core,.so that the peripheral edge `of thelatch` on opposite sides `of the `opening are y freed fromthe rod,`thereby allowing the springytourgey the rod and the pencil core engagedtherebyin a forward i direction. `Forward movement placesthe pencilpoint outQf th eOrWard nose of lthepbarrel.,and` `withinaysharp- Genermounted'in the cap.` Wllen` thefcap is placed over 1 t when the stressesor a combination of stress and tempera-` ture would otherwise damage thematerial or cause it to be deformed within the pencil case.

A still further object` of the present invention is to provide such amarking pencil device which can be formed economically and can be massproduced utilizing eiiicient and economical materials throughout;

The novel features which lare believed to be characteristie of Athepresent invention both as to its organization and method of openation,together with further objects and advantages thereof, will be betterunderstood from the following description considered in connection withthe accompanying'drawing `in which a presently preferred embodiment ofthe invention is illustrated by way of example. It is to be expresslyunderstood,` however, that the `drawing is for the purpose ofillustration and description .to FIGURE l showing the operative partsof4 the device A in the` non-operative `,or fat-rest position at whichtheA pencil t core v ism'retained tlielatch `means Afrom bearing andspaced tpngittidiliany extending slot `11 `fextems fram-the for? warllyfacing shoulder Stijto the'rearward endSS of the [tion into a sharpeningposition, as described more fully hereinafter.

Referring now particularly to FIGURES l, 2, 5 and 6, the elongatetubular support member is a single member formed to provide the nosepiece 24 mateable with the cap section C, and the latch means supportsection Z5 which is positioned within the outer barrel at the forA wardportion thereof. The nose .piece 24 extends a substantial distanceforwardly of the forward end 12 of the outer barrel and is generallycylindrical with a circular transverse cross-section of uniform firstdiameter 40 extending from the forward end 41 of the nose piece to alongitudinal position slightly forward of the forward end 12 of theouter barrel. At a position proximate `the forward end 12 of the outerbarrel, but'spaced forwardly thereof, the tubular support member isincreased indiameter to a second diameter 43 substantially greater thanthe first forward diameter 40 of the nose piece but less than the insidediameter 44 of the `outer barrel. The second diameter 43 occurring atthe longitudinal section proximate the forward end of the barrel is of apredetermined diameter which' is less than the diameter of the innerbarrel by an amount suiiicient to allow the insertion of an actuatingportion of the cap section C. The rst forward diameter 40 and the seconddiameter 43 of the elongate support member are joined by a taperedcircumferential wall 46 which ac-ts as a vguide surface for insertingthecap cylinder over the n ose piece and into the forward end of the outerbarrel, as described more fully hereinafter. Extending rearwardly fromthe portion of second diameter 43, the elongate support member increasesto a third diameter y47 which is substantially equal. to the insidediameter of the outer barrel. The junction of the longitudinallyextending section of second diameter and the longitudinally extendingsection of maximum diameter 47 is defined by a transversely extendingforwardly facing shoulder Sti, which shoulder Si) is spaced inwardlyfrom the outer end of the barrel to define an annular space `51 closedat one end by the shoulder 50 and bounded by the periphery of thesupport member at vthe second diameter 43 thereof and the insidediameter 'd4 of the barrel.

Spaced rearwardly from the shoulder Si) the support ymember is againreduced to a fourth diameter 54 to de-ne a rearwardly facing transverseshoulder 52. The portion of the-member at the diameter 54 extends fromthe shoulder 52 to `the `rearward end 55 of the elongate support member2t).M The fourth `=diameter 54 is slightly less thannthe inside diameterofthe barrel, the difference in diameter being adapted to accommodatethe insertion of the elongate support member 20 -atr the rearwardportion thereof into a thin-'walled retaining `sleeve Iiwlhich extendsfrom a position spaced from the rearwardly facing shoulder 512 incontact with a leg of the latch spring, las described hereinafter, to alongitudinal position proximate the forward end 22 of the sleeve 14 fromthe rearward end 55 of the support member. i v

As shown Iparticularly in FIGURE 6, rst andsecond diametricallyopposedlslots are formed in the support member Vextending fromtherearward end thereof. The Vfirst and second slots are of differentlengths to` accomi mcdate the two legs` of the one-Way latch `springu;The upper o r first slot 6 9 `is sufficient `in width to accommodate theupper leg 64 of the latch spring 65 and extends from the rearwardlyfacing shoulder 52jto tzherearward end interference in its relaxedconfiguration and in the configuration "to which it .is `deformedto'retainytheigpusher rod as described more fullyhereinafter,j` Thesecondorlower fsiipprt] member and isof suiiicientgdepth'at r,theforwardly facing shoulder 5t) tojalmlow .the protrus'ion, of-.thelatcli`spring into the' annular"'spaclewSl;-` Thusgfan opening'iisf `155 ofthe` support member.. The Lradial deptlifof the"rupper provided throughthe support member at the `forwardly facing shoulder 50, which openingis of sufficient width and depth to allow theilower or actuating leg 66of the latch spring 65 to extend froma `position rearwardly of forwardlybeyond the forwardly facing shoulder 50 into the annular space 51.

The latch spring 65 is positioned within the device to allow movement ofthepusher rod and pencil core in one direction only when the latchspring is in the first, or holding, condition as shown in FIGURE 2, andto allow the pusher rod and pencil core to be moved forwardly when thelatchspring is in the second or released condition as shown in FIGURE l.Referring now to FIG- URES '1, 2, 3 and 4, the latch spring 65 Ais agenerally U-shaped spring with an elongate upper leg l64, an elongatelower leg 65, of `greater length than the upper leg, and inintermediate, or base, portion 70 which has an opening 71 extendingtherethrough. The opening 71 is slightly greater in size than thediameter of the pusher rod 116. The base portion 70 of the latch spring,when the latch spring is `in its holding condition, is at anangularorientation relative to a transverse plane extending through thedevice perpendicular to the longitudinal axis thereof.` 4Thatis, thebase .70 is-formed at an acute angle to the upper leg 64 and at acorrespondingly obtuse angle with `the `lower leg 66. Thus, when thelatch spring is deformed `from its holding condition by moving the legsto"po`sition the `base portion closer to a plane normal to` the device,theV circular opening 71 through the base is sufficient `ineffectivesize to allow the free passage of the pusher rod therethrough in bothaxial directions, as shown in FIGURE 3. -In the holding or relaxedcondition of the spring, however, as shown in FIGURE 4, the base portion70 is inclined substantially to the axis of the pusher rod, the-opposite'sides of the base portion defining the opening 71 binding uponand gripping the rod `116,` thereby preventing forward movement of `thepusher rod, since `a force exerted `forwardly on the pusher rod Atendsto move the base 70 to a greater degree of angularity increasing thefrictional 'force between the base and thepusher rod. The latch springwill, however, allow the pusher rod to be moved rearwardly sincerearward forces directed upon the base portion will tend to decrease theangul ."rtpd1t5tlV4 p l Thus, as shown in FIGURES l, 2 and 6, theupperleg 64 of the spring 65 is positioned in the upperslot and islongitudinally fixed therein with the` forward end 72 of the `upper legabutted` against the rearwardly facing shoulder 52 of the supportmember. The'base portion 70 is positioned within the-longitudinally`extending annular Space 73 defined bet-Ween the rearward end of thesupport memberl and the forward end of the sleeve 14. The lower leg oftheA springis greater in longitudinal extent thanthe upper leg, andextends longitudinally within the second ygroove `61 of the elongatesupport member. The forwardedge '74r of the lowerllegof the `springextends through the opening 75. defined` by :the groove in theforwardly"facing shoulders() and for a substantial distance forwardlyofthe shoulder into the annular space 51. The distance by which theforward ed-geof the lower leg ex- `tends` Vinto the annular space isdeter-mined by `the amount of longitudinal movement of the lower legwhich isrequired to Valter the plane gof `the base section 70 of thespringtoward a position substantially normal to the pusher rod "16,"suchthatthqfpusherfrod can` move-freely in both "directionsthroughthelopening 71.` Thus, when thelower legf, at itsfprwardpositionas vshown in FIGURES Ascribedifhereinbeforei"flat,ivhichftheopposedgportions 71a the support member 20 to a position at which itextends arity of the base and release the base from the ofthe`pe,ripheraledgegsurfaceof-the openirigy71yarein ndingpcontaetLvyithlthe` pusher Arod; f Conversely,VV when the forward edge 74 of thelower leg of the spring is moved rearwardly to the shoulder Sil the baseportion 70 is moved toward a plane perpendicular to the axis of' thepusher rod to ll the opposed portions 71a `from the rod,

A thin walled retaining sleeve 80, having an open lorward end and aanged rear-wand end is positioned anound the inner portionof theelongate support member 20` with positionV of the forward 'end 81 of theretaining sleeve.

Normally, however, the sections 90 and 92 move as a unit.

y 'Ilhe cap C is frictionally and releasably held upon the nose piece 24of the barrel A in such manner that it can be retained longitudinallythereon while being freely Y rotatable with respect to the barrel of thedevice. Also, the means lor frictionally bol-ding the cap upon the nosepiece allows sullicient :axial Vfreedom of the capY that it can bern'ovedirom an `assembledat-rest position, vvhere the latch means is inengagement the pusher rod,

The mountingring is thus movable ontothe nose pieceto the position at which the rearward .end a of thejcap'abuts the.forward end of theouter barrel vot the case'.

Accordingly, it can be seen from the rforegoing that operation :of theshaipener D contained within the cap C of the marking -pencil device canbe utilized to sharpen the point or the pencil core only when desired.IIn order to sharpen lthe point, it is necessary only to exert a slightinward force upon the cap C to release the latch and then rotate thecap. Upon release of this force, the cap C is moved `forwardly of thebarrel land the latch suiciently to allow the latch to reengage thepusher rod, preventing the spring trom forcing the pencil B against thesharpener.
